There are actually many kinds of portable small refrigerators, but most of them are semiconductor refrigeration, which is similar to Xiaomi’s mobile phone ice-sealed heat dissipation back clip. The principle is the same. A semiconductor chip is designed to exchange cold and heat within a small power range. .
Disassembly of the ice-sealed cooling back clip
For example, a small refrigerator with semiconductor refrigeration is defined as a dual-use mini refrigerator for the car and home. Indeed, after replacing the power cord, it can be used at home, in the car or even outdoors.

Cold storage box
But this is more like a heat preservation box used by a takeaway delivery person. It does not have the function of refrigeration, and more depends on airtight insulation to maintain the temperature. Usually, the “cold storage box” can absorb heat and release cold to reduce the temperature in the box. The price is relatively cheap, and no power supply is required; however, the cold storage box needs to be charged before use.
